Description
Technical field
The present invention relates to casting films leftover material recycling device.
Background technology
In process of production, rim charge can be cut away after pulverizing this casting films equipment online, is transported to extruder material by blower fanBucket and virgin material enter extruder after mixing again. This hopper is double-decker, and skin is virgin material, and internal layer is powder, and blower fan is carriedPowder enter internal layer hopper by cyclone separator, because powder is low weight, therefore have a compacting screw in the middle of internal layer hopperPowder is extruded into extruder charging aperture and virgin material mixing. As shown in Figure 1: 1 is extruder, 2 is powder compacting screw, and 3 arePowder delivering pipe after fragmentation, 4 is cyclone separator, 5 discharge pipes that are cyclone separator, 6 internal layers that are hopper, storePowder, 7 is hopper skin.
The defect that this device exists is in the time that rim charge width changes, and the powder that is transported to hopper also can change, compacting spiral shellThe bulk density that bar is extruded into the powder of extruder charging aperture also can change, and causes the thickness of film unstable, and works as powderToo much time, powder also can be put up a bridge and cause blanking not smooth at extruder charging aperture.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of casting films leftover material recycling device, realize powderQuantitative conveying, realized the stable of extrusion capacity.
The present invention is achieved through the following technical solutions: casting films retracting device, comprises that the old material being communicated with extruder goes outPipe material and the virgin material discharge pipe adjacent with described old material discharge pipe, also comprise casing, is communicated with old material at described casing upsideConveyance conduit, described old material discharge pipe is arranged at described box house, in described old material discharge pipe, be provided with for delivery ofThe conveying screw rod of powder, described conveying screw rod comprises successively the diminishing First of flight pitch that connects, flight pitch graduallySecond and diminishing the 3rd of flight pitch expanding, described old material discharge pipe has the opening of expansion, described oldMaterial discharge pipe is outside equipped with guard shield, and described guard shield arranges opening, and described casing below arranges base, on described base, arrangesCavity, described cavity is connected with a compressed gas source, is positioned at described old material discharge pipe one side and is provided with described in described guard shieldThe valve that cavity is communicated with arranges a refrigerating plant in described cavity, and described old material discharge pipe is by described cavity.
In technique scheme, described old material conveying tube road is connected with described casing by a cyclone separator.
In technique scheme, described the 3rd and described second 's hand of spiral is contrary.
The present invention has following beneficial effect: the present invention is ejected into old material in casing to have enlarged openings by nozzleIn discharge pipe, because short grained old material is more prone to float to upper strata, therefore ensure to enter the old material base in discharge pipeThis be the old material of uniform granule, ensured old material in conveying screw rod evenly, ensured to extrude stablizing of old material.

Fig. 2 is structural representation of the present invention.
Fig. 3 is the structural representation of guard shield.
Fig. 4 is the structural representation of conveying screw rod in the present invention.
Detailed description of the invention
Below the present invention is described in further detail, referring to Fig. 2 to Fig. 4, a kind of casting films retracting device, comprises and squeezesGo out the old material discharge pipe 2 of machine connection and the virgin material discharge pipe 4 adjacent with described old material discharge pipe 2, also comprise casing 1,Be communicated with old material conveying tube road 7 at described casing 1 upside, described old material discharge pipe 2 is arranged at described casing 1 inside, in instituteState in old material discharge pipe 2 and be provided with the conveying screw rod 8 for delivery of powder, described conveying screw rod 8 comprises the spiral shell connecting successivelyDiminishing the 3rd of second 81 of expanding gradually of the diminishing First 80 of line spacing, flight pitch and flight pitch82, First screw thread charging place flight pitch maximum, old material easily enters thread groove, and bearing capacity is large; Old material is by FirstAfter fully mixing in diminishing thread groove again after entering, enter again in second 81 and disperse, after disperseing in second 81 againIn the 3rd 82, again mix gradually, through the operation of disperseing to mix, ensure that old material can fully mix. Preferably,Hand of spiral in hand of spiral in the 3rd 82 and second 81 is contrary, further ensures mixed effect.
Described old material discharge pipe 2 has the opening of expansion, is outside equipped with guard shield 3 at described old material discharge pipe 2, described inGuard shield 3 arranges opening 30, and described casing 1 below arranges base 5, on described base 5, cavity 51 is set, described cavity51 are connected with a compressed gas source, be positioned at described old material discharge pipe 2 one sides and be provided with and described cavity 51 in described guard shield 3The valve 9 being communicated with. The interior refrigerating plant 6 that arranges of described cavity 51, described old material discharge pipe 2 is by described cavity 51.
Described old material conveying tube road 7 is connected with described casing by a cyclone separator 70, by described cyclone separator 70The powder passing in casing is carried out to initial gross separation, to filter the larger waste material of larger particles and corner wherein, ensure that old material is defeatedSend waste material in funnel evenly. After falling, old material enters into guard shield 3 by the opening 30 of guard shield 3 interior near near valve 9,The air-flow spraying by the valve 9 old material of kicking up, guard shield 3 arranges the baffle plate 31 and the old material that bend inwards and carries in opening 30 upper endsThe opening of pipeline 2 forms the passage passing through for old material, and due to the setting of guard shield 3, old material need to be by entering after opening 30 againValve 9 has prevented that a large amount of old material are blocked in the passage that old material passes through by kicking up.
When use, by described old material conveying tube road 2, the leftover pieces (being old material) after pulverizing are conveyed into described casing 1,Compressed gas source starts, and compressed air is kicked up the old material in casing 1 by valve, and old material falls into discharge nozzle after striking guard shield 3In the opening of 2 upper ends, road, because tiny particle is easily kicked up, therefore drop into the old material granular size of discharge nozzle porchSubstantially close, therefore the old material in conveying screw rod 8 is more even. Old material is being carried rear and virgin material discharging by conveying screw rod 8After mixing, virgin material in pipeline 4 enters extruder.
In described cavity 51, insert a refrigerating plant 6, compressed air is lowered the temperature after refrigerating plant 6, arranges by valve 9Go out, in the old material of kicking up, old material is lowered the temperature, reduce old material frictional heating in conveying screw rod 8, in course of conveyingThe danger of thermal decomposition less, and described old material discharge pipe 2 is by described cavity 51 inside, makes refrigerating plant 6Can lower the temperature to the discharge pipe 2 in cavity 2 simultaneously, more reduce the danger of old material thermal decomposition in conveying screw rod 8.
